Unexpected SimpleDateFormat Behavior

Failing test case:

import static org.junit.Assert.*;
import java.text.*;
import org.junit.Test;

public class DateFormatTests {

  @Test
  public void testRequiredTwoDigitDay() {
      DateFormat df = new SimpleDateFormat("yyyyMMdd");
      df.setLenient(false);
      try {
          df.parse("2009081");
          fail("Expected two-digit day");
      } catch (ParseException e) {
          e.printStackTrace();
      }
  }
}

Argh.

SimpleDateFormat API Javadocs:

For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.

Tricksy API javadocs. We hatessss it forever.
